The optional hub cap removal tool is stowed with the jack. Position the hub cap removal tool in the notch and pull straight away from the wheel to avoid potential damage to the hub cap and wheel surface. Removing the Flat Tire and Installing the SpareTirt Remove the hub cap. If you have an aluminum or plastic molded hub cap, pry it off with the chisel end of your wheel wrench. Some of the molded plastic hub caps have imitation wheel nuts molded into them. The wheel wrench won't fit these imitation nuts, so don't try to remove them with the socket end of the wheel wrench. 1. Using the wheel wrench, loosen all the wheel nuts. Don't remove them yet. 2. Turn the jack handle clockwise to raise the lift head. 5-25
